CRUSHER.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed April 24, 1914. Serial No. 834,045.

To all whom it may concern Be it known that I, THEODORE F. PHILIPPI, a citizen of the United States of America, and a resident of East St. Louis, county of St. Clair, and State of Illinois, have invented certain new and useful Improvements in Crushers, of which the following is a. full,

clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a crusher or pulverizer, one of the objects being to provide an adjustable grate movable toward the crushing element; combined with an adj ustable abutment preferably in the form of a breaker plate engaging an end of the grate and adapted to be shifted to diflerent positions where it will engage the end of the grate after the latter has been adjusted toward the crushing element.

The invention also includes a new rotor structure and certain details of construction which will be hereinafter described.

Figure I is a top or plan view of my crusher. Fig. II is a side elevation partly in section. Fig. III is a vertical section taken approximately on the line IIIIII, Fig. II. Fig. IV is a perspective view of one of the holders for the crushing rollers. Fig. V is a vertical section of the holder, showing the pin slidably mounted in slots in the holder, and the crushing roller mounted on said pin, the pin being positioned in the enlarged ends of the slots through which it may be moved to release the crushing roller from its holder. Fig. VI is a perspective view of one of the crushing rollers. Fig. VII is a perspective view of a pin having a circular middle portion adapted to fit into the roller and having flattened ends adapted to slide in the roller holder.

In the accompanying drawings A designates a casing provided with a top wall 1 and an inlet hopper 2. A rotor provided with crushing rollers is secured to a drive shaft 4:- A sectional grate, arranged below the rotor, is composed of grate sections 5 carried by arms 6, said arms being secured to a pivot rod 7.

8 designates adjusting screws screwed into supports 9 and rotatably fitted to the arms 6 which support the grates. Each adjusting screw 8 is provided with a non-circular upper end, and a head 10 at its lower end.

11 designates a washer interposed between the head 10 and the free end of, the grate supporting arm 6, the washer being provided with a convex upper face which engages a concave face at the end of the arm 6. The screws 8 may be adjusted to shift the grate toward the axis of the rotor.

12 designates abutment screws located adjacent to the adjusting screws 8 and engaging the ends of the pivoted arms 6. These abutment screws serve as means for limiting the movement of the grate, and they maybe screwed downwardly onto the arms 6 to firmly clamp said arms between the washers 11 and the lower ends of the abutment screws. I

The sectional grate is slidably fitted to curved guideways formed in the adjustable arms 6 and the machine isvso constructed that the grate sections slide in said arms when the grate is adjusted toward the rotor. The grate section5 shown in Fig. II at the righthand end of the grate, engages a fixed abutment formed by the top wall of the easing. The grate section at the left hand end of the grate engages a movable abutment in the form of a breaker plate 13. WVhen the grate is shifted toward the rotor the right hand end of the grate is prevented from rising by the fixed abutment 1, andv the grate sections therefore slide in the pivoted arms 6, the left hand end of the grate being elevated as a result of the sliding movement of the grate. The breaker plate 13 abutting against the left hand end of the grate, is adjustably secured to the casing so that it may be moved vertically. The adjustable breaker plate is maintained in engagement with one end of the grate while the opposite end of the grate is at all times engaged with the fixed abutment 1, the object being to prevent material from escaping at the ends of the adjustable grate. The breaker plates 13 and 14 are arranged at the lower end'of an inlet passageway 15 and secured to the casing by means of bolts 16 passing through slots in the casing.

The adjustable grate supporting arms 6 are secured to the casing by screws 6 passing through slots 6 casing. see Figs. II and III. The screws are secured to the arms 6 and provided with heads which lie exteriorly of the casing. These screws guide the long arms 6 in their movements and hold said arms against the side walls of the casing.

in the side walls of the Y A rotatable feeder -17 is arranged in a feeder housing 18 communicating with the inlet passageway 15. This feeder is preferably a cylinder secured to a shaft 19 and provided with feeding fingers 20. The feeder may be shifted from the feeder housing to partially close the inlet opening, the object being to regulate the flow of material by adjusting the feeder,also.to prevent material from being accidentally through the inlet passageway.

The adjustable devices for supporting the feeder include bearing plates 22 serving as bearings for the feeder shaft 19, said bearing plates being slidably fitted to guides 23. The feederishaft 19 extends through slots in the sidewalls of the inlet passageway. The bearing plates are provided with rack teeth 24 meshing with pinions 25, the latter being secured to a shaft 26. e

27 designates a hand. wheel secured to the shaft 26 for the purpose of shifting the feeder toward and away from the wall 28 of the inlet passageway. The hand wheel 27 may be operated to turn the pinions 25, thereby sliding the bearing plates 22 which carry the feeder. The adjusting mechanism for shifting the feeder may be locked indifferent positions by a locking pin 29 adapted to pass through any one of a series of apertures 30 in the hand wheel. 27, see Figs. 11 and III.

31 designates a keeper secured. to the machine housing and adapted to receive the locking pin 29. It will now be understood that thefeeder may-be adjusted to different positions in the inlet passageway 15 and that it may be securely held in position by the locking pin 29.

The means for driving the adjustable feeder while it-occupied different positions in the inlet passageway comprises a sprocket wheel 32 secured to the feeder shaft 19,-and a chain 33 for driving said sprocket wheel.

A shaft 34 arranged above the casing A is secured rotatably mounted in bearings 35 to a pivot rod 36.

37 designates a sprocket wheel secured to the shaft 24 and meshing with the sprocket chain 33. The shaft 34: is driven through the medium of a large pulley38 secured to said shaft,-a small pulley 39- secured to the main drive shaft 4 and a belt 41-0 passing around said pulleys 38 and 39. The pivoted bearings 35 carrying the shaft 34: may be adjusted to tighten the belt 40 or to stop the feeder driving mechanism, by the adjustment of screws 41 passing through the pivoted bearings 35 and engaging the top.

The drive chain 33 wall of the casing A. passing around the sprocket wheels 32 and 34 is flexed between said sprocket wheels as seen in Fig. 11 and this chain is free to yield in response to an adjustment of the feeder 17. A weighted chain tightener as is pivote discharged ally supported at Mend provided atits free end with a roller 45 which lies upon the chain 33.

The rotor, or rotary crushing element of my machine comprises side members preferably in the form of large disks secured to the drive shaft 1 and located near the side walls of the casing A. Transverserods 51 carried by the side disks 50 are arranged in apertures in said disks and held i in position by removable plugs 52 screwed into the apertures and engaging the ends of the transverse rods 51. Crusher holders are formed by a series of slotted frames 53 31". ranged in pairs and secured to the transverse rods 51, each of said slotted frames being supported by three of the rods 51. Each crusher holder consists of two of the slotted frames 53 and rivets 5st connecting said frames.

55 designates crushingrollers arranged in the crusher holders and rotatably mount-v ed on pins 56,ithe latter being provided with circular middle portions for the reception of the rollers and reduced ends which lie within the slots 57. The enlarged middle portions of the pins 56 arearranged directly between the slotted frames 53 and the fiattened ends of said pins are closelyfitted to the walls of the slots 57 to prevent the pins from turning. The crushing rollers and the pins 56 are freeto slide toward and away from the axis of the rotor and the inward movement of said parts is limited bythe rods 51 at the inner ends of the slottedlOO frames 53.

In-removing the crushing rollers and pins 56 from the machine the first step is to remove =the rods 51 which normally form abut- I ments for retaining these parts in the ma- 105 chine, and after these rods are removed the rollers and pins maybe moved to the posi tion seen in dotted lines at the lower portion: of @Fig. 11 and in full lines Fig; V. The pins are then alined with the enlarged inner 11 ends of the keyhole slots 57 and the rollers may be released from their holders by withdrawing the pins 56 through the enlarged inner ends of the slots.

All of the transverse rods 51 which sup-: 1 port the crushing: elements, are .removably secured to the large side disks 50 by the removable plugs 52 (Fig: 111) and the side walls of the casing Aare provided with apertures 60 through which theaods 51 may be withdrawn from: the, rotor. After the rods 51 have been removed from the rotor, the crushing rollers and their holders are released from the rotor and a section of the casing may be removed to. permit the removal of said rollers and holders.
